Grab an animal of your choice and bite its head off.. its that easy. =)
Water is your best friend, either for washing or for drinking. Organic is a good way to go. Broccoli, believe it or not, seems to taste pretty good raw and is one of the best overall foods. Of course, fruits and nuts are good too. I would suggest making sure to get a good balance of whatever you eat and drink lots of water. Good luck.
don't eat anything cooked
